 When installing any  optional equipment, make sure that the SRS system is not damaged. Do not attempt to service
any  component  of the SRS yourself. Attempting to do so may result in serious personal injury. If a  problem arises,
take your car to the nearest authorized Volvo retailer for inspection as soon as possible.
pg. 5 Front  airbags - SRS
A self -diagnostic system incorporated in the sensor monitors certain safety system components. A check is performed
on components such as seat belt locks, SRS, SIPS,  and/or the VIC system. If a  fault is detected, the warning light will
illuminate. The light is included  in the warning/indicator light cluster in the instrument panel. Normally, the safety
system warning lamp should light up when the ignition key  is turned to positions I, II or III and  should go out after
approximately 7 seconds or when the engine is started. Check that this  light is functioning properly every time the
vehicle is started.WARNING!
 Never  drive an  SRS equipped car with your hands on the steering wheel pad  / airbag housing.
 No objects, accessory  equipment or stickers may be  placed on, attached to or installed near the SRS cover in the
center  of the steering wheel, the SRS cover above the glove compartment or the area affected by airbag deployment.
 If the SRS warning light stays on after the engine has started or if it comes on while you are driving, drive the car
to the nearest authorized Volvo retailer for inspection as soon as possible.
There is no maintenance to perform on the SRS yourself. The month and  year shown on the decal on the door pillar
indicate when you should contact your Volvo retailer for specific servicing or replacement  of airbags and  seatbelt
tensioners. This service must  be  performed by an  authorized Volvo retailer.
Should you have any  questions about the SRS system, please contact your authorized Volvo retailer or Volvo

NOTE: Volvo's dual-threshold airbags  use special sensors  that are integrated with the front  seat buckles. The point
at which  the air bag  deploys is determined by whether or not the seat belt is being used, as well as the severity of the
collision.  Collisions can occur where  only one  of the airbags deploys.
NOTE: Volvo's dual-stage airbags: If the impact is less severe, but severe enough  to present a  clear  injury risk, the
dual-stage airbags are triggered at just  70% of its  total capacity. If the impact is more severe, the dual-stage airbags are
triggered with full capacity.

WARNING!
 Children must  never be  allowed in the front  passenger  seat. Volvo recommends that ALL  occupants (adults and
children) shorter than 4 feet 7 inches (140 cm) be  seated in the back seat of any  vehicle with a  front  passenger -side
front  airbag. See  page 16
 for guidelines.
 Occupants in the front  passenger's  seat must  never sit  on the edge of the seat, sit  leaning  toward the instrument
panel or otherwise sit  out of position. The occupant's back must  be  as upright as comfort allows and  be  against the
seat back with the seat belt properly fastened.
 Feet must  be  on the floor,  e.g.  not on the dash, seat or out of the window.
 No objects or accessory  equipment, e.g.  dash covers, may be  placed on, attached to or installed near the SRS
hatch (the area above the glove compartment) or the area affected by airbag deployment (see illustration on page 4
).
 There should be  no loose articles, e.g.  coffee cups, on the floor,  seat or dash area.
 Never  try to open  the SRS cover on the steering wheel or the passenger  side dash. This should only be  done  by an
authorized Volvo service technician.
 Failure to follow these instructions can result in injury to the vehicle occupants.
pg. 8 Front  airbags - SRS
NOTE : The information on this  page does not pertain to the Side Impact Protection System  airbags.
When are the airbags deployed?
The SRS system is designed to deploy during certain frontal or front -angular collisions, impacts, or decelerations,
depending on the crash severity, angle, speed and  object  impacted. The SRS sensor is designed to react  to both the
impact of the collision  and  the inertial forces  generated  by it and  to determine if the intensity  of the collision  is
sufficient for the airbags to be  deployed.
WARNING!
The SRS is designed to help prevent serious injury. Deployment  occurs very quickly and  with considerable force.
During normal deployment and  depending on variables such as seating position, one  may experience abrasions,
bruises, swellings, or other injuries as a  result of airbag(s) deployment.
If the airbags have been deployed, we recommend the following:
 Have the car towed  to an  authorized Volvo retailer. Never  drive with the airbags deployed.
 Have an  authorized Volvo retailer replace  the SRS system components.
 Use only new, Genuine Volvo Parts when replacing SRS components (airbags, seat belts, tensioners, etc.).
When are the airbags NOT deployed?
Not all frontal collisions activate the SRS system. If the collision  involves a  nonrigid object  (e.g., a  snow drift or
ProCarManuals.com 

SIPS airbag (front seats only)
As an  enhancement to the structural Side Impact Protection System  built into your car, the car is also equipped with
Side Impact Protection System  (SIPS) airbags. The SIPS  airbag system consists of airbag modules built into the sides
of both front  seat backrests (1), wires (2) and  gas generators/sensor units  (3). 
The SIPS  airbag system is designed to help increase occupant protection in the event of certain side impact collisions.
The SIPS  airbags are designed to deploy only during certain side-impact collisions, depending on the crash severity,
angle, speed and  point of impact. The airbags are not designed to deploy in all side impact situations.
NOTE: SIPS  airbag deployment (one airbag) occurs only on the side of the vehicle affected by the impact.
WARNING!
 The SIPS  airbag system is a  supplement to the Side Impact Protection System  and  the three-point seat belt system.
It is not designed to deploy during collisions from  the front  or rear of the car or in rollover situations.
 The use of seat covers on the front  seats  may impede  SIPS  airbag deployment.
 No objects, accessory  equipment or stickers may be  placed on, attached to or installed near, the SIPS  airbag
system or in the area affected by SIPS  airbag deployment (see illustration below). 
 Never  try to open  or repair any  components of the SIPS  airbag system. This should only be  done  by an  authorized
Volvo service technician.
In order for the SIPS  airbag to provide its  best protection, both front  seat occupants should sit  in an  upright
position with the seat belt properly fastened.
 
1 - Airbag, 2 - wire, 3 - gas generator/sensor unit
WARNING!
 Never  drive with the airbags deployed. The fact that they hang  out can impair the steering of your car. Other
safety systems can also be  damaged. The smoke and  dust formed when the airbags are deployed can cause skin and
eye irritation in the event of prolonged exposure.
 If your car has been subjected to flood conditions (e.g. soaked carpeting/standing water on the floor  of the
vehicle) or if your car has become flood-damaged in any  way, do not attempt to start the vehicle or put the key  in
the ignition before disconnecting the battery. This may cause airbag deployment which  could result in personal
injury. Have the car towed  to an  authorized Volvo retailer for repairs.
*A SIPS  airbag warning decal is also located at the end  of the instrument panel on the driver's side of the car.

Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an  octane rating AKI of 91,
or above. AKI (ANTI KNOCK INDEX)  is an  average of the Research Octane Number, RON, and  the Motor Octane
Number, MON. (RON  +  MON/2).
The minimum octane requirement is AKI 87 (RON  91).
Deposit control gasoline  (detergent  additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be
effective in keeping injectors  and  intake  valves clean. Consistent use of deposit control gasolines will help ensure good
driveability and  fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with
the service station operator.
Unleaded fuel
Each Volvo has a  three-way catalytic converter and  must  use only unleaded gasoline. U.S. and  Canadian regulations
require that pumps delivering unleaded gasoline be  labelled "UNLEADED".  Only these pumps have nozzles which  fit
your car's filler  inlet. It is unlawful to dispense  leaded fuel into a  vehicle labelled "unleaded gasoline only". Leaded
gasoline damages the three-way catalytic converter and  the heated oxygen  sensor system. Repeated use of leaded
gasoline will lessen  the effectiveness of the emission control system and  could result in loss of emission warranty
coverage. State and  local  vehicle inspection programs will make detection of misfueling easier, possibly resulting in
emission test failure for misfueled  vehicles.
NOTE: Some U.S. and  Canadian gasolines contain  an  octane enhancing additive called methyl-cyclopentadienyl
manganese  tricarbonyl (MMT). If such fuels  are used, your Emission Control System  performance may be  affected,
and  the Check Engine light (malfunction indicator lamp) located on your instrument panel may light. If this  occurs,
please return your vehicle to an  authorized Volvo retailer for service.
Gasoline containing  alcohol and ethers
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates"  which  are usually alcohols or ethers. In some areas, state or
local  laws require that the service pump be  marked indicating use of alcohols or ethers. However, there are areas in
which  the pumps are unmarked. If you are not sure whether there is alcohol  or ethers in the gasoline you buy, check
with the service station operator. To meet  seasonal air quality standards, some areas require the use of "oxygenated"
fuel.
Volvo allows the use of the following "oxygenated" fuels; however,  the octane ratings listed on this  page must  still  be
met.
Alcohol - Ethanol: Fuels containing up to 10% ethanol  by volume may be  used. Ethanol may also be  referred to as
Ethyl alcohol,  or "Gasohol".
Ethers - MTBE: Fuels containing up to 15% MTBE may be  used.
CAUTION!
Do not use gasolines containing methanol (methyl alcohol,  wood alcohol). This practice can result in vehicle
performance deterioration and  can damage critical parts  in the fuel system. Such damage may not be  covered under the
New Vehicle Limited Warranty.

Carbon Monoxide - Important  Warning
Carbon  monoxide is a  poisonous, colorless, and  odorless gas. It is present in all exhaust gases. If you ever smell
exhaust fumes  inside the vehicle, make sure the passenger  compartment is ventilated,  and  immediately return the
vehicle to your retailer for correction.
